実験手順

To a solution of {2-[5-amino-2-(3,5-dimethylphenyl)-1H-indol-3-yl]ethyl}-[4-(4-amino(dimethanesulfonyl)phenyl)butyl] carbamic acid tert-butyl ester (from EXAMPLE 3.2 StepC, 60 mg in 3 mL dry methylene chloride) at 0° C. was added 0.025 mL pyridine followed by 0.020 mL acetic anhydride and the mixture stirred at low temperature. After 15 minutes, the reaction was quenched by the addition of saturated aqueous sodium bicarbonate and extracted with ethyl acetate. The organic portion was washed successively with a pH2 solution, saturated sodium bicarbonate and brine, then dried over sodium sulfate. Concentration in vacuo provided the crude title compound (65 mg).
